Color Portrait #2

I wanted to follow the time-lapse drawing process of Vincent Chu (https://www.youtube.com/watch?v=lsRbX2ScLGQ&t=1s) because I liked the image and wanted to understand how he drew this. Also drawing of the hair was one of the biggest challenges which I still need to work on. 
But overall it was fun. Started to experiment with different brushes. 
Drawing time: 8 hours.
